Application filed July 19,

T 0 all wlw/m, t may concern Be `it known'that l, BUDD KENT, a citizenof the United States, residing at loodburm in the county of Marion andState of Oregon, have invented certain new and useful Improvements inClod Crushers, of which the following is a specification.

This invention` relates to clod crushers andl soil pulverizers and hasfor its object the provision of an implement by the vuse of which theclods in a field will be effectually'broken. up and pulverized andthesur'- face soil reduced to a fine mulch ready for plantingY and inproper condition to facilitate a healthy growth of plants.'V The in-lvention is illustrated in the accompanying drawings and will behereinafter fully set forth.

Inthe drawings- Figure 1 is a perspective view -of ya may y v l f causethe same to ride up' o r down 1n the.

chineY embodying my improvements;

Fig 2 is a side elevation of the same with one ground wheel and the endof the frame adjacent: the same remo-ved;

Fig. 3 is a plan view of the lower frame and the parts mounted thereon;

Fig. 4 is a detail elevation of the adjustable bearing for the groundwheel;

Fig. 5is a horizontal section through the saidbearing;

Fig. 6 is a The main frame of my improved machine comprises end or sidebars 1 and a rear transverse barv 2 connecting the same, a front crossbar 3 also connecting the end or side bars, and forwardly convergingbars 4 eX- tending from the front ends of the bars 1. A.l clevis orother draft-attaching device 5 is provided at the front ends of theconvergingbars 4, and afoot rest or platform 6 is carried by the saidbars and the front cross bar 3, a caster 7 being connected with theplatform 6 so as to aid in supporting the'sarne, as shown` andas will bereadily understood. Arched bars 8 extend between and are secured to thecross bars 2 and 8 and support a seat 9, as shown. An axle or drivingshaft 10 is rotatably fitted in the side or end bars 1 and extendsentirely across the machine, the ground wheels 11 being fitted upon theends of the axle and connected therewith by escapement devices,indicated at 11, whereby, upon forward travel of the machine, the axlewill be rotated but upon backward movement the axle detail view of anescapernent.v

will remain at` rest. Upon? thelairle, between the``s1de, bars 1, I-secure a beatingcylinder consisting of discs12 and toothfbars or fstripsy 13 extending across kthe edgesI of the said discs and securedrigidly thereto, teeth or pins 14 being carriedby and Projectingradially from the said bars 13, as clearly shown. rFitted around theaxldwadjacent ir ounce,

the bars l `are'bearing frames'l-iri the side edges of which are grooves"whichy slidablyy receive the sidefrnembers of inverted U-`shapedvstandardsll'v and. a jack. screw 18 is Vfitted `through thefheadof'this stand# ard and swiveled therein, thelowerpforti'on of the said'screw4v having, threaded' engager ment with the upper end ofthe bearingframe 15. A handfwheel 19 is provided at the upper end `of the ackscrewsoI that the screw maybe easily rotated', anditwill be readily seen thatrotation of the screwwill head' of the bearing frame and therebyeffect,"`

vertical movementA of' the standard. `The standard is yduplicated at thetwo. sides of the machine andthe upper 'ends ofthestandards areconnected by'a cross beam 20; The lower ends of the standards 17 areri'gidly secured to the end or side bars 21' of thel lower frame. Thebearings 36 for the axle or driving' shaft are securedto the sidebars-1, as indicated/in Fig. 5, andare rowhich ymaybe provided withvafshar'p front edge wherebyit will cut readily through the ground andturn over weeds and roots in i the surface of thesoiltas well as :liftclods of dirt. The front extremities of the bars `21 are tapered, asclearly shown in Fig. 2,

to facilita-te their passage through the soil, and sifter `rods 24aresecured at their front ends to the cross plate 23 and 'extendtherefrom past the cross bars 25, 26 and 27 toy which they are secured.These rods 24 are disposed longitudinally of the frame yand are somewhatclose together and preferably consist of stout wjires. The matter turnedup by the blade 23 will be deposited upon these rods and the motionotthe machine in traveling over the field will produce sufficientvibration to cause the fine soil to sift between the sitter rods and bedeposited upon the ground in a finely pulverized condition. The beatingcylinder will, ot course, rotate with the ground wheels 11 and therotation ot the cylinder will cause the teeth i4 thereof to ride againstthe larger clods upon the sitter bars 24 and break up the same intoparticles which will readily drop through the spaces between the saidbars. In rear ot the cross bar 27, l provide a cross bar 28 constitutinga rake head which is provided at its ends with pintles or truniiions 29journaled in bearingsBO upon the bars. Rake teeth 3l are secured to andextend rearwardly from the rake head 2S and ride upon the ground so asto collect weeds and other trashwhich may be upon the surface'ot thesoil. Ahand lever 32 is secured rigidly tothe rake head and extendsupwardly therefrom in rear of the seat 9 and is adapted to engagelocking teeth 33 formed upony the adjacent archy 8. Byswin'gingptheupper end ot the said lever 32 forwardly, the rake will berocked and theaccumulated weeds and trash will thus be cleared ot therake teeth and may be subsequently easily gathered and destroyed.

` Mounted upon the cross bar 8 is a hand lever 3a and a rod 39 connectssaid hand lever with the beam 20. It `the lever 34; be swung forwardly,the standards 17 and the lower trame will be tilted about the axle 10and the blade 23 thereby caused to run at a greater or less depth, aswill be readily understood. A chain 4:0 is attached to the beam 20 ateach end thereof and at the rear edge of the same, the chain beingengaged over a bolt 4101i the adjacent bar 1 to limit theforward tiltinget the standards and the lower frame.

The usel of the machine will be readily understood from the foregoingdescription, taken in connection with the accompanying drawings, and itwill be readily noted that I have provided a very simple and compactmechanism whereby clods will be easily loosened from the surface ot thesoil and ettectually pulveriZe-d so that, after the machine has traveledover a field, the surface of the tield will be in proper condition forthel growth of lhealthy plants.

Having thus described the invention, what is claimed as new is:

1. A clod Crusher comprising a main trame, wheels supporting said trame,a beater cylinder mounted in said trame concentric with the wheels andactuated thereby, and a sitter trame arranged below the beater cylinderand carried by the vfirstmentioned trame and adapted to run below thesurface of the ground and litt the soil and clods to be acted upon bythe beater.

2. In ay clod Crusher, the combination of a main frame, wheelssupporting said trame, a beater cylinder mounted upon said trameconcentric with and actuated by the wheels, and a sitterframe arrangedbelow and carried by the main trame and comprising a blade, side barsextending rearwardly fromv the ends ot" the blade, cross bars secured toand extending between the side bars in rear of-the blade, and sitterrods secured at their front ends to the blade and extending rearwardlytherefrom under the beater cylinder in parallel spaced relation andsecured tothe said cross bars. A

3. ln a clod Crusher, the combination of a main frame, an axle mountedin and extending across said frame, wheels fitted upon the ends ot theaxle to support'the trame and actuate the axle, a beater cylindercarried by the axle within the frame, a sitter frame arranged below themain frame, bearing frames encircling the axle adjacentthe main frame,standards secured to and rising from the ends ot the sitter trame andslidably engaging the said bearing trame, and jack screws havingthreaded engagement with the bearing trames and swiveled in thestandards whereby the sitter trame may be tilted and adjustedvertically.

4L. ln a clod Crusher, the combination of a wheel-supported main trame,a beater mounted upon the mainframe, a sitter trame disposed below themain frame and extending under the beater, standards rising from theends of the sitter trame through and above the main trame and mountedfortilting movement upon 4the main trame, a connection between saidstandards, and alever mounted upon the main frame and operativelyconnected with the connection between the standards.
